T all whom it may concern.

Be it known thatI, ERASTUS E. VVINKLEY, a citizen of the United States, residing at Lynn in the county of Essex and State of have invented certain new Machines; and lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for leveling the soles of boots and shoes, and more particularly to machines of this type which comprise a leveling device and a cooperating shoe supporting jack a relatively movable to cause a progressive transfer of the pressure over a shoe sole. v

Owing to the varying curvature of different portions of a last bottom some portions of the shoe solerequirea more extended leveling action than others if the entire sole is tobe shaped into conformity with the curvature ofthe last.

Theobject of the present invention is to provide a machine for leveling thesoles of boots and shoes which operates efiiciently to cause all portions of thesole toconform to. thecurvature of the last without exerting an excessive pressure upon any portion of the last, during the leveling operation.

WVith this object in view, one feature of the inventionvcontemplates the provision in a a machine of the class described having a leveling device and a cooperating shoe supporting jack, cally varying pressure exerted upon the shoe sole. I a e a 7 Still further'features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages ofwhich will be obvious to those skilled in the art from the following description; g

In ,the accompanying drawings illustrating the preferred form of the invention-:'

jack after a pre'cleterminedtime has elapsed ,ri ais a detailshowing a plan view partly n-section of the mechanism illustrated in Fig. 2; and Fig. 5 is a detail showing upon an enlarged scale the cam for controlling the starting mechanism.

The illustrated embodiment of the invention is showntin connection with a machine of the type disclosed in the patent to Winkley, 555,548, patented March 3, 1896. This machine is provided with the usual shoe supporting jackl pivoted at 2 in the machine frame 3 and oscillated through suitable connections by a cam secured to the cam shaft 5. The leveling device consists of a freelyfrotatable roll 10 journaled in the outerend of'a roll supporting arm 11 and connected to an eccentric 12 which imparts a rapid vibratory movement to the roll as the jackis moved thereunder. The .arm 11 is pivotally supportedv at 13 and a cam 14 is connected to the roll through mechanism fully shown and described in the patent above referred to. for tipping the roll to change the relative lateral inclination of the roll and jack as the latter is moved beneath theroll. The cam shaft 5'has a worm wheel 15 secured thereto which is engaged by a driving worm 16 mounted upon the counter shaft 17. The shaft 17 is operated from a drive shaft 18 through a pair of 1ntermeshing spiral gears 19 and 20 secured toxthe shaft 18 and loosely journaled upon the shaft 17 respectively. The shaft. 17 is r clutched to the gear, 20 through a clutch collar 22 splined to the shaft 17 and arranged to engage with a cooperating clutch member 23 secured to the gear 20. The clutch-g collar 22 is actuated by a sliding clutch rod 24: connected with a treadle 25 at one end and with theclutch 22 at its opposite end so that upon a depression of the treadle25 the clutch collar is disengaged from the member 23, stopp1ng the rotation d of the shaft 17. Therod 2 1 is normally moved to maintain thelclutch collar 22 engaged by a compression spring 27 interposed between the frame of the machine and a collar 28 secured to the rod 24.

In the. majority of shoes the transverse curvature ofthe last bottom varies COIlSid-r erably at different shoe and in order to cause all portions points lengthwise of the the sole 'to oaform substantially shape of the last without exerting an excessive pressure, itis 'desirab1e,. to vary the extent of 'theleveling action upon difi'erent portions of the sole.

secured to the cam by bolt and slot connections indicated at 62. The cam 55 is engaged by the free end of a lever 57 fulcrumed at-58 and having its opposite end connected to a slide 59 through a link 60. The slide 59 is loosely mounted upon the rock shaft 37 and a spring 61 normally retains the slide in a retracted position, as shown in Fig. 3. With this construction, when the end of the lever 57 engages with one of the cam ribs 56, it is oscillated to move the slide 59 in a longitudinal direc- This movement of the slide posi tions the traveler member opposite different portions of the lead screw 89, consequently varying the length of traverse of the member. Each of the ca1ns56 is located in advance of its correspondingfinger in order to position the traveler member properly with relation to the lead screw 39 before the member is moved into engagement there 'with; It will be noted that the normal position of the traveler member 88, which is determined by theengagement of the lever 57 with the face of the cam 55, is beyond the commencement of the lead screw thread. The purpose of this arrangement is to enable the machine to be automatically stopped at the completion of the cycle of operations without setting into operation the mechanism for restarting the jack. To this end in the illustrated embodiment of the invention, one of the fingers 30 is not provided with a corresponding cam rib 56 and when this finger moves into engagement with the dog 31 to operate thetrain of mechanism for stopping the machine, the free end of the lever 57 is positioned as shown in Fig. 4, causing the traveler member 38 to move into engagement with the cylindrical end of the lead screw 39, stopping themachine for an indefinite length of time until restarted by the operator.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention.
